This invention relates to improvements in waste receptacles, and particularly to the type designed to afford a safe and sanitary depository for material which, because of odor or 'for 5 other reasons, is deemed' objectionable.

It is an object of the invention to provide an article of this character which is substantially air-tight when in closed position and yet opens readily with a minimum of effort, rendering accessible the waste-receiving portion thereof.

A further object is that of providing a receptacle in which the cover, when in open position, is shifted away from any danger of being soiled when waste is deposited within the receptacle.

Another object is that of providing an article of this type which is extremely flexible in its adaptation and renders itself available for many uses.

Still another object is that of providing a waste receptacle which has the maximum capacity while occupying a minimum of space, and which is at the same time pleasing in appearance.

With these and other objects in mind, reference is had .to the attached sheets of drawings, and in which:

Fig. 1 represents a cross-sectional View, taken along the line l-i of Fig. 2, of one form of receptacle with an inner waste-receiver in position; i

Fig, 9 is a. fragment of a receptacle in cross (Cl. 22o-36) section, showing a still further modification of the cover-actuating mechanism.

Referring now primarily to Figs. 1 through 4 we have a receptacle formed with a semi-circular forward wall l0 and a dat rear wall l! so that in appearance the receptacle resembles half of a conventional cylindrical can. The receptacle is provided with a base I2 and a retractible side door I3 which is mounted by means of a supporting member I4 which, in turn, is pivoted at Iii to a bracket I carried by the rear wall of the receptacle. The door likewise is guided in its movement by means of a rail member il positioned directly behind the front wall of the receptacle and which provides a groove or trackway for the top of the door i8 to travel in. The door is also provided with a handle member I9 with which it is readily moved from open to shut position. The receptacle base is mounted at its forward edge to the front wall of the receptacle by means of a bracket 2l), rubber or similarly covered, which additionally acts as a stop member to limit the extent of travel of the member I4, thus preventing the door from being" opened too far. The upper portion of the front wall of the receptacle is curved inwardly at 2l andhas a shoulder 22 at its upper edge. A receptacle cover 23 in the form of a segment of a hemisphere is mounted by means of a supporting arm 2li which is pivotally secured to the walls of the 30 receptacle at Z5. A handle 23a is secured to the cover so that it may be opened by hand, if desired. In place of the handle 23a a rail member might be formed, extending across the upper edge of the cover so that the user could open e5 the cover from any position. The cover is also formed with a bead 26 at its lower edge which strikes against a cushioning member 2l of rubber or other suitable material which is secured to the under side of the shoulder 22, thus noiselessly limiting further upward movement of the cover.

The rear wall of the receptacle is likewise provided with a shoulder 28 under which the'top or forward edge of the cover projects, and a 45 rubber or other bead member 28a is fastened to the under side of the shoulder, thus aiording a seal at this point for the parts. It will be noted that the cover is so proportioned that it does not strike against the rear wall il of the 50 container but is arrested in its movement, just short of this point by the engagement of the bead 2@ with the cushioning member 2l.

Extending from the supporting arm at right angles thereto adjacent the point of pivot ,oi

the arm, is a bell crank lever 29 which has coupled to its outer end a spring 30. The free end of the spring is fastened to the pivot mounting 3| which is, in turn, secured to the rear Wall of the receptacle. Likewise, pivotally secured to the outer end of the bell crank lever at 32 is a pull rod 33 which extends downwardly to a point adjacent the base of the receptacle, where it has secured to it a foot pedal 34. The pedal extends rearwardly and is pivoted to the base of the can at 34a and to the connecting link of the pull rod at 34h. The link, in turn, extends outside the receptacle through an opening 35 formed in the side wall thereof. In operation, the foot pedal 34 is depressed, carrying with it the pull rod 33 which, in turn, causes the bell crank lever 29 and the supporting arm 24 to pivot at 25, carrying with them the cover 23, so that it assumes the position shown by the dotted lines in Fig. 1.

It is to be noted that by spacing the horizontal radius 36 of the cover vertically with respect to the point of pivot of the supporting arm 25, the cover is maintained, when in open position, at a point where the bead 26 projects inwardly only to a slight degree from the vertical plane in which it is positioned when the cover is closed. Thus, the full interior of the receptacle is available to the user with a minimum danger of soiling or contaminating the inside of the cover member. After the waste material has been deposited into the inner waste receiver 31, which may be of any well known construction, the foot is removed from the pedal 34, which raises the bell crank lever 29, thus bringing the cover back to closed position.

Referring to Fig. 5, there is disclosed a cylindrical type of receptacle having an outside wall in the form of a semi-circle, and a complementary inner side wall member 8| to complete the cylinder. A base ring 82 is secured to the outer side wall, and extending across the bottom thereof is a supporting strap 83 which is riveted at 84 to the ring. This strap is formed with a pivot or bearing opening in its center. Secured to the lower edge of the inner side wall is a cylindrical platform 86 which carries a pivot member 81 for cooperation with the pivot opening before mentioned. An inner receptacle of any desired character is placed on this platform, which rotates about its point of pivot, causing the inner wall 8| to telescope with respect to the outer wall 80. A handle member 88 may be secured to the one edge of the inner wall to facilitate opening and closing the same. The pedal 89 is pivoted to the base ring at 90 and is secured to the pull rod 9| at 92. This pull rod extends upwardly along the outside of the receptacle and is coupled to a cover mechanism, as already described in connection with Figs. l through 3. In a cylindrical receptacle, it is apparent that a plurality of cover portions might be provided all opening simultaneously by means of one actuating lever, or independently of each other by the provision of independent actuating levers. Likewise, a plurality of inner containers or waste receivers might be provided, one for each of the cover portions.

In Fig. 6 we find a modification of the receptacle in which there is provided a cylindrical receptacle with a side wall 50 and two independent cover members 5| which are spaced at the center by means of a partition Ela, which extends above the uppermost limit of the cover portions and has a handle aperture 5|b at that point. This partition, in turn, may be utilized in securing the receptacle to a wall 52, so that, for example, a receptacle might be placed in an opening out in the common wall of two rooms or compartments, and one-half would be accessible to the occupant of each room or compartment. Likewise, as shown in Fig. 6, the foot pedal might be in the form of a continuous rail member 53 extending halfway around the receptacle, so that it might be operated from any position with respect thereto. As shown in the broken away portion of Fig. 6, instead of providing an inner waste receiver, the receptacle might be formed with a base 54 upon which is positioned the receptacle proper 55, which is a complete can unit formed with its rear wall slightly lower than the forward wall, as at 56. Cooperating therewith is a shoulder 51 of the nonmovable portion of the cover 58, which shoulder provides for a seal between the cover and the receptacle. A movable cover 59 would also be provided and would operate in the usual manner.

Referring now to Figs. '1 and 8, we have a receptacle formed with a base 60 and side wall members 6| which are hinged at 62 to form door portions opening outwardly to allow access to the interior of the receptacle. These door portions have handles 63 to facilitate their opening. The cover 64 is supported, as heretofore described, by means of a supporting arm 65, which, in turn, is pivoted at 66 to a bracket 61, secured to the frame of the receptacle. A bell crank lever 68 is secured to the lower end of the supporting arm adjacent the point of pivot, and a pull rod 69 extends downwardly to the foot pedal 10. Pivoted to the rear wall of the receptacle at 1| is an arm 12 which engages, at its free end, the bell crank lever 68 and which carries at its other end, a weight 13. In operation, it will be noted that by depressing the foot pedal 10 and carrying with it the pull rod 69, the bell crank lever and supporting arm will be pivoted about the point 66 opening the cover member. As the bell crank lever moves downwardly, it will carry with it the arm 12, thus causing it, in turn, to pivot at 1| and raise the weight 13 which is carried at its other end. As soon as the foot is removed from the pedal 10, the weight 13 will immediately tend to move downwardly, causing the rod 12 again to pivot at 1| and to engage the under side of the bell crank lever 69 and raise it upwardly, thus returning the cover to its closed position. If `desired, the bell crank lever 68 and the arm 12 may be directly coupled to each other in a well known manner.

As shown in Fig. 9, the counter-balance actuating mechanism for the cover might be arranged so that the supporting arm |00 is pivoted at |0| to the frame of the receptacle which is formed by the rearwardly extending arm |02, t`o which is supported a weight |03. When the cover |04 is lowered, either by means of a handle or a foot-actuated mechanism of the type heretofore disclosed, the arm |02 and the weight are raised, and when pressure is released from the cover, the weight tends to return to its initial position, carrying with it the cover. A well or shaftway |05 is provided for the weight, so that it will be protected from outside interference. This well is formed by adding a false rear wall |06 to the receptacle.

It will, of course, be apparent that the invention herein described might be carried out with equal success in a container or receptacle of any desired shape, and the applicant does not wish to be restricted to the particular forms illustrated, but desires that all matter contained in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense. Likewise, many changes in construction and rearrangements of the parts might be resorted to without in the slightest departing from the spirit of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
